The SoInt32Element class is the base class for elements that simply store a 32-bit integer.
This is the superclass of elements where the new element data replaces the old data, and where the data the element stores is a simple 32-bit integer value.
This element is like a convenient light-weight version of the SoReplacedElement. It differs from the SoReplacedElement in that the set() and get() methods are already implemented, since it is known that subclasses will still contain just a single 32-bit integer value.
void SoInt32Element::initClass | ( | void | ) | [static] |
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoElement.
Reimplemented in SoTextureUnitElement, SoGLShadowCullingElement, SoShadowStyleElement, SoAnnoText3CharOrientElement, SoAnnoText3FontSizeHintElement, SoAnnoText3RenderPrintElement, SoComplexityTypeElement, SoDecimationTypeElement, SoDrawStyleElement, SoGLDrawStyleElement, SoGLLightIdElement, SoGLLinePatternElement, SoGLTexture3EnabledElement, SoGLTextureEnabledElement, SoLightModelElement, SoLinePatternElement, SoMaterialBindingElement, SoNormalBindingElement, SoPickStyleElement, SoSwitchElement, SoTextOutlineEnabledElement, SoTextureCoordinateBindingElement, SoTextureEnabledElement, SoUnitsElement, and SoVertexAttributeBindingElement.
SoElement * SoInt32Element::copyMatchInfo | ( | void | ) | const [virtual] |
This function creates a copy of the element that contains enough information to enable the matches() function to work.
Used to help with scenegraph traversal caching operations.
Implements SoElement.
void SoInt32Element::print | ( | FILE * | file | ) | const [virtual] |
This function is for printing element information, and is used mostly for debugging purposes.
Reimplemented from SoElement.
void SoInt32Element::set | ( | const int | index, |
SoState *const | state, | ||
const int32_t | value | ||
) | [static] |
FIXME: write doc.
SoInt32Element::data [protected] |
The 32-bit integer value of the element.
